Hi everybody - we love when you see small things like lichens, mosses, smaller plants, bugs, insects, and other critters, but if you want to help to ID these to species or genus, you need to provide good photos. Photographing small things are sometimes not easy, but there are some hints:
Even a cheap digital camera usually has a macrosetting, use it. Make sure you are not too close so that the photo becomes blurry.
If you use a smart phone or tablet, get a clip-on macrolens - they are under $10 on Amazon, or use a regular handlens that you hold in front of your phone/tablet.
Example for clipon lens from Amazon (not endorsed): WONBSDOM®3 in 1 Universal Clip on Lenses Kit Black) with FishEye Lens+Macro+Wide Angle Lens
Example for handlens from Amazon (not endorsed): SE - Loupe - Triplet, LED Illuminated, 10x, 21mm
Crop your photos: before uploading them to iNaturalist, use a simple editing program (or edit directly on your cameras/phones/tablets), to crop out the areas around your species that are not relevant. Better to show exactly what you are talking about here. For example, a picture of a tree trunk might have 3 lichens on it, so take the photo and make 3 photos out of it, so we know which organism you mean.
And, when taking photos light is always important. When you use extra lenses for macro, a simple little LED flashlight will help you a lot in getting better photos.
A clean background is always nice for sessile or dead critters - for living, moving ones, you can sometimes get them into a jar so it will be easier to take a photo then.
Take photos from several directions - top, side, bottom! Often characters are only visible from one directions.
Good luck!
